Abstract
Slaughterhouse wastewater is one of the most produced industrial wastewater in the world. This wastewater can cause a high level of pollutant effect when the process is given to riverbeds or sewage systems without any treatment. Wastewater contains proteins, fats, carbohydrates in the treatment of blood, skin and feathers, which results in much higher biological oxygen demand (BOD) and chemical oxygen content (COD) In this study, the use of wastewaters with high organic, nitrogen (N) and phosphorus (P) as an agricultural product has been examined. In addition to these results, the Life Cycle Analysis (LCA) of the ultrafiltration system was also carried out. Accordingly, the effects of ultrafiltration system on human health, ecosystem quality, climate change and resources were calculated as 0,00000046 DALY, 0,134 PDFxm2yr, 0,336 kg CO2 eq and 6,937 MJ respectively. In the light of the results, it is thought that the wastewaters of the slaughterhouse industry can be used as irrigation water after passing through the ultrafiltration membrane because of the high amount of N and P.
屠宰场废水是世界上产生最多的工业废水之一。这种废水在未经任何处理的情况下被排放到河床或污水系统中,会造成高度的污染效应。在处理血液、皮肤和羽毛的过程中,废水中含有蛋白质、脂肪和碳水化合物,导致生物需氧量(BOD)和化学氧含量(COD)大大增加。本研究对高有机、氮(N)和磷(P)废水作为农产品的利用进行了研究。除了这些结果,超滤系统的生命周期分析(LCA)也进行了。据此,超滤系统对人类健康、生态系统质量、气候变化和资源的影响分别为0,00000046 DALY、0,134 PDFxm2yr、0,336 kg CO2 eq和6,937 MJ。综合研究结果,认为屠宰业废水中氮磷含量较高,可作为灌溉水通过超滤膜后使用。
